About SJWD The South Carolina General Assembly passed Act 1105 creating the SJWD Water District, a special purpose district, in 1956. The legislation established the District's boundary and provided the authority to sell bonds. Over the years the District has grown. Today its service area covers approximately 128 square miles in western Spartanburg County. The service area stretches from Highway 417 in the South, to Highway 11 in the North, and from I-26 in the East to the Greenville County line in the West. As of January 2006, the District served approximately 20,000 accounts and a service area population of approximately 45,000 people. The Middle Tyger River (Lyman Lake), and the North Tyger River (Lake Cooley and North Tyger Resevoir) are the sources of water for SJWD customers. Water from these rivers is treated at the SJWD Filtration Plant on Groce Road in Lyman.
